python - 类型 Error/login authenticate() 接受 0 到 1 个位置参数，但给出了 2 个

Question

def loginUser(request):
    if request.method == "POST":
        username = request.POST.get('username')
        password = request.POST.get('pass1')
        user = authenticate(username, password)

        if user is not None:
            login(request, user)
            return redirect( '/')

        else:
            messages.error(request, "Either your email or password is wrong!")
            return render(request, 'loginpage.html')
    return render(request, 'loginpage.html')

每当我在登录页面上输入凭据时，就会出现此错误，我的登录函数也被命名为 loginUser 呢

    username = request.POST.get('username')
    password = request.POST.get('pass1')
    user = authenticate(<b>username=</b>username, <b>password=</b>password)
    # …
